major reservoir of sulphur

There are six main categories of air pollutants: oxides of carbon sulphur dioxide oxides of nitrogen hydrocarbon inorganic particulate matter and aerosols organic particulate matte..

Sulphur Cycle - Sulphur is an important component of most proteins, few vitamins and enzymes. Though sulphur occurs in gaseous form, as hydrogen sulphide (H 2 S) and sulphur dioxide (SO 2 ), the residence time of sulphur in atmosphere is very small ..

1) Decomposers like Aspergillus (aerobic fungi), Neurospora (aerobic fungi) and Escherichia (anaerobic bacteria) act on the dead and decaying organic matter of plants and animals, releasing hydrogen sulphide (H 2 S) to the environment. 2) Heterotrophic bacteria like Desulfavibrio and Acetobacter r..

(i) Most of the sulphur produced is used for the manufacture of sulphuric acid and other industrially important sulphur compounds. (ii) Sulphur is used to prepare large number of medicines (Sulpha drugs) and can be used as ointment for curing skin diseases. (..

Sulphur dioxide is a dangerous air pollutant because of its corrosive properties; it irritates the eyes, nose, and lungs. It is produced by combustion of coal, fuel oil, and gasoline, since these fuels contain sulphur. The sulphur content of a fuel can be reduced by re..

Hydroelectric power stations can cause some major problems. Large dams must be built to hold the water before it flows to the turbine. This causes ecological imbalance. At times small pieces of earth get trapped at the bottom of still water in the reservoir. As these deposits bu..

Adverse Effect of Sulphur Dioxide on Environment - Sulphur dioxide is a dangerous air pollutant because of its corrosive properties; it irritates the eyes, nose, and lungs. It is produced by combustion of coal, fuel oil, and gasoline, since these fuels contain sulphur...

Types of Biogeochemical Cycles - Biogeochemical cycles are basically of two types: a) Gaseous cycles like carbon (as carbon dioxide), oxygen, nitrogen, etc. b) Sedimentary cycles like sulphur, phosphorus, etc. In gaseous cycles, the elements have a main reservoir in the gaseous ..

Sulphur occurs in the earth's crust to the extent of 0.05% mostly as metal sulphides and sulphates. It also occurs in the elemental form in large underground beds. Another major source of sulphur is H 2 S present in the natural gas and crude oil. Sulphur exis..

Minerals are inorganic nutrients. They include both metallic and non-metallic elements, which are taken by the body in the form of salts. There are 24 elements that are used in our body. They have various functions such as formation of tissues such as the bone, conduction of nerve impulses, f..
